Supplier Mech Flanged Resilient NRS Gate Valve (Z45X)

WWW.DISTRIBUTORALATINDUSTRI.COM | The Flanged Resilient NRS Gate Valve (Z45X) is a non-rising stem gate valve designed for reliable isolation service in water supply, fire protection, HVAC, and industrial piping systems. It features a fully EPDM or NBR rubber-coated resilient wedge that provides bubble-tight sealing, low operating torque, and long service life. The non-rising stem (NRS) design minimizes installation space requirements, making it ideal for underground and confined installations. The valve body is typically manufactured from ductile iron with a fusion-bonded epoxy coating for superior corrosion resistance and durability.
